Every car enthusiast faces such a problem as a dead battery. Most often, the cause is winter cold: low temperatures adversely affect the operation of an electrochemical device. During the urban driving cycle, the generator is not able to replenish the battery capacity to the required level. Yes, and unplugged lights lead to battery discharge. It is for such cases that a charging and starting device has been created that can not only charge the battery, but also ensure the start of the car engine. Many car enthusiasts have already tried and appreciated the functionality and indispensability of this device.
There are several parameters that you need to rely on when choosing a charger for your car:
- output voltage (different for batteries for trucks and cars);
- starting current (the operation of the starter at start-up depends on its value);
- charging current (here it is necessary to focus on the capacity of the battery, for alkaline batteries it is four times less than the capacity, for acid batteries it is ten times smaller).
By type and purpose, devices are divided intocombined, household and professional appliances. The simplest is a household charger-starter. Its components are a powerful transformer, an output voltage regulator, a diode bridge and a conventional ammeter. Despite its simplicity, this device has a lot of drawbacks, the most important of which is the lack of protection against typical human errors. Confusion in connecting the battery poles will short circuit and damage the device. The optimal battery charging mode also leaves much to be desired.
Reliable professional starting charger is equipped with protection against short circuits and incorrect connection of the poles, it is possible to automatically adjust the charging current, use reverse charge and voltage stabilization system. Such equipment is necessarily equipped with special clamps with which it is connected to the battery terminals. A high-quality charger and starting device is multifunctional, has many advantages in design, is distinguished by high power and the ability to recharge several batteries at once. You can break it only in case of improper use, for example, connect it to the battery using a bare wire, not a clamp.
The most difficult to operate is the combined charger and starter. This fixture is an advanced welding machine equipped with a voltage divider. The maximum voltage of the device inwelding mode can reach 50 - 70V, and necessary to replenish the battery - 12V or 24V, so do not forget to switch the toggle switch to the charging or engine start mode. If this is not done, then the device will easily disable the electronics and wiring of the car.
When choosing a charger-starter, you must also consider the method of charging the battery. If the current is constant, it is faster, but battery life is reduced. And if recharging occurs at a constant voltage, then the battery is quickly discharged. The best option would be devices that, during charging, first stabilize the current, then the voltage, and your car battery will last longer.
